Abstract

An electric drive performance is highly influenced by the potential of the controller employed. For high-performance Permanent Magnet Synchronous Motor (PMSM) drive, Vector control techniques are preferred over other methods. Due to the non-linear dynamics and time-varying parameters of PMSM, its control is a significant issue. This paper investigates the application of a fuzzy logic controller for the speed control of Field oriented PMSM. The Fuzzy Logic is based on the speed error and change of error measured as the difference between the motor speed and the reference speed. The Fuzzy Logic controller performance is also compared to a PI controller. It's been observed that the Fuzzy Logic controller gives better response for speed control of PMSM drive as compared to the PI controller.
